emLib
Cryptography and Data-Integrity Modules for any Platform
Collection of cryptography and data-integrity modules including CRC and ECC
Optimized for high performance and minimal memory usage
Portable ANSI C implementation for embedded systems and PC applications
Key features
Simplicity and Consistency
emLib's API is simple, consistent, and easy to use across all modules. The same API can be used in PC applications and embedded targets, which simplifies development and testing procedures.
High Speeds, Minimal Space
emLib delivers high speeds, but requires only minimal memory space, making it optimal for resource-constrained embedded systems.
Cross-Platform Flexibility
Because it is written in ANSI-C, emLib is easily ported to virtually any CPU or architecture. It works with devices that range from 8 to 64 bits in size.
How emLib Works
emLib consists of independent modules that can be added to a project as needed. Each module uses a consistent API, and this allows users to initialize with the required parameters, process data, and retrieve results. Since all memory is provided by an application, resource consumption is predictable.
Data-Integrity Modules
CRC Library
Handles arbitrary polynomials up to 32 bits wide in both normal and bit-reversed form. In addition to providing generic CRC functions, emLib CRC features optimized implementations for popular CRC polynomials, including CRC-CCITT, CRC-16, and CRC-32.
ECC Library
Provides routines for the detection and correction of multiple bit errors, and includes implementations for 4-, 8-, 24- and 40-bit error correction.
Licensing
The software is available under various embedded software license models and can be delivered as source code. All commercial licenses are based on a one-time payment, are royalty-free, and include six months of updates and support for SEGGER's Embedded Experts.
There are no subscription fees, ensuring predictable and fixed costs over the entire product lifetime.
